Think of the brain as a city. If you were to look out over

a city and ask “where is the economy located?” you’d

see there’s no good answer to the question. Instead, the

economy emerges from the interaction of all the

elements ― from the stores and the banks to the

merchants and the customers. And so it is with the

brain’s operation: it doesn’t happen in one spot. Just as

in a city, no neighborhood of the brain [ ].

In brains and in cities, everything emerges from the

interaction between residents, at all scales, locally and

distantly. Just as trains bring materials and textiles into

a city, which become processed into the economy, so

the raw electrochemical signals from sensory organs

are transported along superhighways of neurons. There

the signals undergo processing and transformation into

our conscious reality. [3점]
